Diesel EGR Coolers
Not sure which part you need? Use our parts-request checklist.
Diesel EGR coolers route a portion of hot exhaust gas through a coolant-fed core, lowering its temperature before it re-enters the cylinders to reduce NOx and help your engine meet emissions targets. When the core cracks, plugs, or starts leaking coolant, you get overheating, white smoke, and coolant loss fast. JAK'S Diesel stocks EGR coolers for heavy-duty and Class 8 diesel engines, with PAI aftermarket and OEM-quality options.
Not sure which unit fits? We cross-reference OEM, competitor, and superseded part numbers so you order the right cooler the first time. Browse the units below, then call or text us for fitment help.
